Chemical and Biological Studies on TwoHelichrysumSpecies of Greek Origin

Abstract: The chemical composition of the essential oils obtained from the aerial parts of Helichrysum amorginum and H.italicum were analysed with GC and GC/MS. From the twenty-five identified constituents representing the 89.98% and 82.06% of the two oils respectively, geraniol, geranyl acetate, neryl acetate, and nerolidol were the major components. Furthermore, it was found that the oils exhibited definite antibacterial activity against the six tested Gram (+/-) bacteria.

“…GC/MS analysis identified neryl acetate (28.2%) and g-curcumene (18.8%) as the main compounds while neryl propionate (9.1%) and ar-curcumene (8.3%) existed in significantly lower concentrations [22]. Oil extracted from H. italicum collected in Greece contained high amount of geraniol and geranyl acetate [23]. Furthermore, three different chemotypes for the essential oils of H. italicum were described: one was rich in nerol, another contained the majority of α-and β-selinene and the third chemotype was characterized with high concentration of γ-curcumene [24].…”

“…Este metabólico volátil, o mais abundante e comum entre os óleos essenciais analisados, influi em seu aroma e possui diversas atividades biológicas, tais como, anti-inflamatória, antialérgica, anestésica local, antifúngica e anticarcinogênica. 9,10 No óleo essencial das folhas de A. panurensis foram detectados principalmente os hidrocarbonetos sesquiterpênicos b-cariofileno (33,5%), germacreno-D (25,4%), a-copaeno (7,5%) e b-bourboneno (7,1%). A somatória dos demais terpenos encontrados neste óleo equivale a menos de 10% da sua composição total.…”

“…O espatulenol, além de influir no aroma de muitos óleos de interesse comercial para a indústria de perfumes, possui propriedade antibacteriana e moderada atividade citotóxica contra células do tipo KB. 10,11 O potencial da atividade antioxidante dos óleos foi determinado com base na atividade sequestrante do radical livre estável 2,2-difenil-1-picril-hidrazil (DPPH). Todos os óleos apresentaram atividade varredora de radicais livres em ensaios qualitativos, realizados em placa cromatográfica (Tabela 2).…”
